/OBJECTIVES: Vertebral artery hypoplasia is a common congenital anatomical variant of the vertebral arteries, traditionally considered a benign finding. However, accumulating evidence suggests that VAH may influence vertebrobasilar hemodynamics and contribute to susceptibility to posterior circulation disorders....

Discussion
Signed responses from readers of the wire.
No actionable change for audiologists at this time; the review is relevant to understanding posterior circulation anatomy but has no direct implication for audiology clinical practice.
Posterior circulation problems can manifest as dizziness or sudden hearing loss, so understanding vascular risk factors like vertebral artery hypoplasia may inform differential diagnosis in vestibular and audiology clinics.
- 01Vertebral artery hypoplasia (VAH) is a common congenital variant where one vertebral artery is abnormally narrow.
- 02Systematic review synthesized epidemiological, hemodynamic, and clinical evidence on VAH's posterior circulation risks.
- 03VAH is linked to vulnerability in posterior brain circulation, which may contribute to ischemic events.
- 04Symptoms of posterior circulation compromise include dizziness and sudden hearing changes, overlapping with audiology presentations.
- 05Evidence base characterizes VAH as a clinically underrecognized anatomical risk factor.
Vertebral artery hypoplasia is associated with increased vulnerability of the posterior cerebral circulation.
